I fixed it. Cart works!
I am so happy because months of frustration, i just finish it by myself. I am so rukie in this but fixed it. My cart page was not redirect because I delete the cart page and made new cart page. I upgrade then downgrade I try all support forum.
I finally wrote to the plugin author, still no respond been weeks now!
Then I decided to delete Woocommerce. No choice!
I only delete all the cart, checkout pages but not the product pages.
When i delete Woocommerce i noticed on my homepage I have 3 menu home ,cart and blog.
Bingo that was the cart was bothering me bcoz it was not Woocommerce those 3 pages I made that's y it was still there!
I reinstalled the same plugin and I have all my product pages were saved in there.
When I add that product in the cart.
My cart worked!
I just missed few setting sales tax and new page which I know how to setup again.
Please do this step when you have no choice or solution left!
Mine works so I thought I should share.
